linking with libexpat.so

[William Trenker]

I have a strange problem that is trivial to reproduce as shown here:

~/libtool# libtool --version
ltmain.sh (GNU libtool) 1.5 (1.1220 2003/04/05 19:32:58)

~/libtool# libtool --mode=link gcc -o test test.o -rpath /usr/lib -L/usr/lib 
-lpng -lexpat
gcc -o .libs/test test.o  -L/usr/lib -lpng /usr/lib/.libs/libexpat.so 
-Wl,--rpath -Wl,/usr/lib
gcc: /usr/lib/.libs/libexpat.so: No such file or directory

Notice how the linker reference for the expat library has been rendered as 
"/usr/lib//.libs/libexpat.so".  Of course there is no such subdirectory as 
"/usr/lib//.libs/".  Yet the reference to libpng.so is simply -lpng as expected.

Both libexpat.so and libpng.so are installed in /usr/lib as shown here:

~/libtool# l /usr/lib/{libpng.so,libexpat.so}
lrwxrwxrwx    1 root     root           17 May  5  2003 /usr/lib/libexpat.so -> 
libexpat.so.0.1.0*
lrwxrwxrwx    1 root     root           19 Nov 10 23:45 /usr/lib/libpng.so -> 
libpng12.so.0.1.2.4*

I'm mentioning this problem because I've seen it come up on more than one 
occasion when simply downloading and trying to build pretty common software.  
It happened again today when I tried to build fontconfig-2.2.0.  Before running 
off to the fontconfig folks to ask about this I thought I'd try the small test, 
above.

Can you tell me what I can do to circumvent this problem?  Do you think it's a 
configuration anomaly on my system?  I've been trying to find the answer in the 
rather involved debug trace and config listing that I've attached below.

Thanks very much,
Bill
